Hi there

I'm having hard times getting video to play straightaway on my N770 (2006). I start Canola and go into my videos, click on one of them and have to wait ages (3-4 minutes) before it starts. Sometimes the first frame shows after about 2 minutes. As soon as it opens it plays smoothly and when I choose another video it starts immediately, so it's just the first time the video player starts. After I quit Canola and start it again the same thing happens. I have tried fiddling with virtual memory setting but it doesn't seem to be of any help .
When I play the videos in Mplayer they play just fine, I only have to wait 2-3 seconds before they start.
Has anyone experienced similar problems? I'm not quite sure whether it's a bug or N700's hardware limitations.
I use the latest Mplayer as well as Python 2.5
Other than the videos everyone works great.

I would like to thank handful and the team for creating this awesome piece of software. Keep it up!
Hi roberto,

It seems that we are hitting against a mix of canola2 architecture x platform architecture x device limitations.

Talking with the guys, they told me that is probable that When canola talks to it's media engine (ATABAKE, which takes care of who is going to play a media file) it uses DBUS, and it's possible that DBUS messages are being delayed between this communication, thus it takes time to mplayer start. Also the fact that also maybe happening some swap of memory thus leading to more delays (as canola is not a light application)

We received this complaint, and we will investigate further.. but if we come to a conclusion that to help this we need to change too much in the architecture (and it's not needed for the 2 newer devices) unfortunately we don't go that way, as we want to promote the platform not run against it.

But if in the future these bottlenecks starts to appears to much we will try to come up with something.

Anyways this are the suspects, and we will investigate further to see what we can do!
